2 SHEETS-SHEET Z- JOHN HIIQDEBRAND, or YONICERS, NEW YORK ELECTRIC SIGNALING. DEVICE.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed June 12 1915. Serial No. 33,769.

To all whom it may concern 1 Be it known that I, JOHN HILoEnnxxn,

a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented new and useful Improvements in Electric Signaling Devices, of which the following is a specification.

The invention relates to an-electric signaling device for boxes, and more particularly to the class of burglar proof jewelry boxes or cases.

The primary object of the invention is the provision-of a box or case of this character wherein when the cover or lid thereof is unlocked and an attempt is made to open the same an audible signal or alarm is sounded, thereby indicating malicious tampering therewith.

Another object of the invention is the provision of a box or case of this character herein should an attempt be made to move the same when at rest for the carrying away thereof an audible signal or alarm will be sounded, thus iving notice of the theft or malicious handling of the same for the hiding of such case or box to evade discovery.

A further object of the invention is the provision of a box or case of this character which is simple 1n constructlon, novel in form to assure against theft or burglariz-' ing of the same, thoroughly reliable and efficient in operation, and inexpensive in manufacture.

\Vith these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will 'be hereinafter fully described, illustrated in Fig. 5 is a diagrammatic detail view of the circuit with the circuit closer switch, battery and audible alarm.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail,'the

box or case comprises a body 10 having a hinged lid or cover 11, while within the body is a series of spaced vertical and trans versely disposed partitions 12 forming a number of compartments, certain'of which are adapted to receive jewelry, silverware, or other valuable articles, the walls of the compartments for the latter and the inner surface of the lid or cover being covered with a plush or velvet lining 13 as usual to protect the articles and to give an attractive appearance to the interior of the box.

The front wall of the body 10 is fitted with a suitable key-operated lock 14 which engages a keeper 15 on the lid or coverll so that it may be securely fastened closed.

Within one of the remaining compartments, upon a wall thereof, is secured an electric bell 16 which is arranged in a normally open electric main circuit 17 including the battery 18, which is held in another of the remaining compartments, and within this circuit are the posts 19 and 20, re-

holding said circuit closer open, the arm 21 being connected with a tension spring 23 which actsthereon to automatically operate the closer when the lid or cover is open for closing the circuit to sound the bell as a signal.

Arranged in shunt with the main circuit 17 by the wires24 is another circuit closer comprising an annulus 25 connected with one of the wires 24, the said annulus being fixed to a hanger or bracket 26 secured to the body above the bottom thereof, while secured to the latter and located centrally relative to the annulus 25 is a guide stem 27 having its base 28 secured to the bottom of the body and connected with the other wire 24, and slidable on the stem is a plunger 29 which is formed with resilient fingers 30 for bridging the annulus 26 to close the electric main circuit.

' Surrounding the stem 27 is a coiled expansion spring 31 which acts upon the plunger 29 to bring the fingers 30 thereon into contact-with the annulus 25, the said plunger being formed with a head 32 having a concavity providing a seat 33 for a ball 34 which by its own weight resists the tension of the spring 31 to normally hold the finger 30 disengaged from the annulus to sustain the main circuit open until the ball is displaced from its seat, whence the ball will bridge the space between the head of the plunger and the said annulus 25 closing the circuit to the same and the ball, the latin this manner close the main circuit, which in both instances causes the sounding of the bell'for a signal. 4

The main circuit has arranged therein a hand operated cut-off switch 35 of the ordinary well-known construction so that the bell and the circuit closer can bec 'endered inactive when the box is to be used by the possessor.

Provided in one or more sides of the body 10 are a plurality of openings or holes 36 which emit the sound from the bell when the main circuit is closed so as to make it clearly audible without the box or case, and thereby indicating the malicious tampering therer a with.

From the foregoing description, taken in connection with the accompanying drawings, the construction and manner of operation of the device will be clearly understood, and therefore a more extended explanation has been omitted.

What is claimed is 1. The combination with a signal and an" displaced to engage the annulus to bridge the circuit.

2. The combination with a signal and an electric circuit controlling the same, of a normally open switch arranged in the circuit, a plunger connected with the switch and adapted to be actuated by a movable part for the opening or closing thereof, a circuit closer including a post connected with one leg of the circuit, an annulus connected with the other leg of the circuit and disposed concentrically of the post, a ball carried by the post and adapted when displaced to engagethe annulus to bridge the circuit, and means on the post and forming a holder for the ball and adapted to bridge the circuit from the said post to the annulus independently of the ball when relieved of its Weight.

In testimony whereof I affix my signature in presence of two witnesses.
